Referee Lee Probert failed to spot the incident, but the Football Association reviewed it and hit the Cottagers defender with a ban.

The outcome was welcomed by the Gunners boss : "I am 100% [supportive], because you wouldn't like to think that somebody could escape dangerous play just because it hasn't been seen well by the referee and misjudged by the referee.

"This sacrosanct rule that once it has been judged by the referee nobody can come back [and be punished] means you could be a killer just because the referee doesn't have the perfect angle to see what you did.

"I completely support that and the players knowing that this can happen will only improve the situation."

The Fulham defender has since apologised to the 18-year-old Januzaj , saying that his stamp was born out of "frustration".

"It was very unlike me and I can only say that frustration got the better of me," said Riether.

"I also want to apologise to my team-mates, fans and everyone at the club for the ban incurred following Saturday's match.

"I will accept the consequences of my actions, and hope to put it behind me when I return.

"I want the fans to know that I will be working hard to stay fit and will be ready to continue fighting for the club as soon as I am able."
